NSB-- "Non Stud Book" ("NTB" in Australian Stud Book) female lines not admitted into the Australian Stud Book because the pedigrees of the foundation mares were lost or otherwise unprovable. Herbert Wanklyn and A.F. Howarth compiled a list of such families in 1949, as did Douglas Barrie in the 1950s. These are different from the so-called Colonial families only in that they were not deliniated in the Bobinski and subsequent Shirai family tables.
